Isn’t it trivial to show impossible colors in VR by texturing an object in different colors like blue and yellow for each eye’s perspective?



Some interesting work around this research paper:

Oh wow, these options are really cool. Some of them are hard to see, but even the experience trying is interesting.


My vision seems to oscillate between both eyes in the example picture shown (the yellow-blue one) - in the overlay, the colour changes from yellow to blue and back, with an overlay inbetween. If I concentrate I can see yellow over a blue background consistently though.

Does anyone have the same or a very different experience?

I imagine something similar would happen with your proposal, and possibly make people sick.

(Mixing vision between eyes is really interesting. My eyes are really different (one is good for close-up, one better for distance) so I have some experience with this.)


For me it is blurred yellow-blue striped tape that goes slowly from left to right (idk why, but since you mentioned, my right eye is a little ‘for close-up’). Sometimes one eye takes over and I see just one of the colors.


Traditional displays (such as what would be used in vr goggles) do not produce yellow light. You only get reddish-green with rgb colors


Technically you could make such an extended gamut OLED screen, 4-stimulus. Probably RBGY variant. Some such screens are on the market already but they do not really produce superior results. Some phone screens use RBGW pattern too.


Not really, if you look at the CIE chromaticity diagram, you’ll find that the experience of spectral yellows are very closely approximated by an RGB monitor. It’s spectral cyan that is really out of gamut for a standard display. Take a photo of a green traffic light (which is a little cyan so colorblind people can see it’s not red). I’m pretty sure that green-light color is out of gamut for most displays. https://en.wikipedia.org/wiki/SRGB


Your comment inspired me to look at my phone under a microscope (I opened a paint program's color picker).

As with many things I have examined under a microscope, I didn't actually learn anything new, but it was still interesting to see for myself.


Crap, guess we’re stuck with reddish green :(


Artist Sterling Crispin has a VR painting program [1] that explores this allowing you to paint different colors to each eye simultaneously.
